How did the solar system form?

Solar system formation began approximately 4.5 billion years ago, when gravity pulled a cloud of dust and gas together to form our solar system.

Scientists can’t directly study how our own solar system formed, but combining observations of young stellar systems in a range of wavelengths with computer simulations has led to models of what could have happened so many years ago.
